Don't mount it. Read it directly with tar. After all you wrote a tar archive to the disk not a filesystem (as has already been pointed out). While its probably not what you intended to do, its what you told the computer to do. Try "tar -tvzf /dev/acd1c" and see what happens. It should work without mounting the CD. Another thing: jpeg and gif pictures don't compress as they are already compressed. Gzip'ing the tar archive at best will make it only a bit bigger, not smaller. However, gzip adds another layer of validation if you are concerned about the archive dropping a bit sometime in the future. While gzip will shout loud and clear that the archive is broken it may be impossible to recover. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
